  • Patent number: 11457714
    Abstract: A hair dryer system includes a hands-free dryer having a base, an air flow generator that causes an air flow, and a heating element in contact with the air flow. The hands-free dryer includes a nozzle through which the air flow exits the hair dryer, and an actuator that is physically coupled to the base and to the nozzle, and that moves the nozzle in at least one degree of freedom relative to the base. The hands-free dryer includes an actuator driver circuit that drives the actuator according to a user-selected one of a plurality of stored alternative user-selectable oscillation modes. The hair dryer system also includes a user interface, optionally pertaining to a hair-styling tool, that is in communication with the actuator driver circuit. The communication identifies to the actuator driver circuit the user-selected one of the plurality of stored alternative user-selectable oscillation modes.

  • Patent number: 11460249
    Abstract: Embodiments provide a multi-pass kiln with two or more chambers, an entrance and an exit at a proximal end of the kiln, and a reciprocal flow path extending through the kiln from the entrance to the exit. Lumber charges traveling along the reciprocal flow path may travel in a first direction along one side of the heated second chamber before traveling in a substantially opposite second direction along the opposite side of the second chamber. The distal end of the kiln may be substantially sealed, and a pressure differential between the distal end and the proximal end may draw moist heated air from the heated chamber toward the exit and entry to preheat and/or condition lumber charges traveling through the first chamber.

  • Patent number: 11452353
    Abstract: The present invention is directed to an aid to help consumers with long hair to more efficiently and evenly dry their hair at one time. A system, device, technique and kit are envisioned that allow a consumer to either adapt existing hair drying equipment for this enhanced purpose or provide entirely new systems or kits to enable the consumer to evenly dry their hair. Extension members threadably engage to each other and a hair dryer or bonnet, the combined elements when mounted to or on a stand allow a user to control, adjust and guide the airflow around long hair of the user inserted into a tunnel portion of the extension members. A heat distribution conduit provides even heat to the deployed hair, and a stand or mount are employed to stabilize the assembly.
